+objective function given by the expectation of some appropriately chosen
+utility function with respect to the joint distribution of unknown
+quantities (including responses).  This objective function is usually not
+available in closed form and the design space can be continuous and of high
+dimensionality.  This package uses @dfn{Approximate Coordinate Exchange} (ACE)
+to maximise an approximation to the expectation of the utility function.")
